Description

Detailed description

  The present invention relates to a destination control system for an elevator group, in which a destination call is input to the destination control system via at least one destination call input device, and one of at least one elevator group of the elevator system. Assigned to the above elevators and providing destination calls. The advantage of the destination control system that assigns hall calls to elevators in the elevator group is that the elevator control identifies not only the destination floor but also the departure floor, and as a result, the elevator system fully recognizes the operation route and the elevator for the hall call. It is in facilitating the assignment. In recent years, destination control systems also provide a pre-reserved destination call option part that includes correlated operating times for destination calls as well as departure and destination floors. Through such means, the destination control system identifies the presence of landing calls from a very early stage and, therefore, the elevator to further meet the cost function criteria commonly used for optimal allocation of landing calls to elevators. The operation in the system can be organized. The cost function typically includes parameters such as passenger waiting time, passenger boarding time, total travel time, energy consumption. The assignment of hall calls with an assignment algorithm using a cost function is known per se and will not be described in further detail. The cost function ensures call assignment that selects the elevator that is best suited to handle calls taking into account cost function optimization criteria.

  The problem with the destination control system, including the advance reservation function, is that the advance reservation function is only used by a small number of users, while the advance reservation call sometimes did not reserve a call, so the advance reservation and elevator car To be used by people who are not authorized to board.

  Accordingly, it is an object of the present invention to provide an improved destination control system that is more amenable to use of the advance reservation function than currently known destination control systems.

This object is solved by a destination control system according to claim 1, an elevator group control device according to claim 13 , an elevator system according to claim 14 and a method according to claim 16 . Preferred embodiments of the invention are subject to the protection of the corresponding dependent claims.

  Some inventive embodiments are also described in the specification part of the present application. In particular, the content of the present invention may consist of separate inventions if the invention is considered from the point of view of descriptive or implied subtasks, or from the point of view of advantages or obtained advantages. In this case, the features included in the following claims can be redundant from the standpoint of a separate inventive concept.

  According to the present invention, each pre-reserved destination call is correlated with the departure floor, the destination floor and the correlation time for the pre-reserved destination call as well as the correlation of the user who reserved the pre-reserved destination call. Also includes an identifier. This identifier is manually input by the user, for example, via the keyboard of the destination input panel. The identifier may also be entered using an identification card or identification tag or using a personal destination call input device such as a portable device such as a mobile phone. In this case, the identification of the portable device uses the uniqueness of the individual destination call input device to permit transmission or detection of the user identifier. According to the present invention, pre-reserved calls are always associated with individual persons.

  By associating a pre-reserved call with a specific identifier, it becomes possible to verify later whether a pre-reserved call was really used by the person who sent the pre-reserved call.

  The priority handling in the simplest embodiment is simply to distinguish between pre-reserved calls and non-pre-reserved (immediate) calls. Higher priority in call assignment for pre-reserved calls can be obtained by various means. On the one hand, the priority of pre-reserved calls may be increased by securing at least one specific elevator in the elevator system, or only calls pre-reserved for at least one elevator in the elevator system A predetermined space may be secured. On the other hand, in addition to this method or as an alternative to this method, the destination control system sets the weighting factor of the cost function parameters used for call allocation for pre-reserved calls to be different from that for immediate calls. You may adjust. As a result, parameters such as the waiting time of the passenger and the ride time change. In this case, it is possible to reduce the passenger waiting time, the ride time or the total travel time of the call reserved in advance. This correlates with a kind of special status for pre-reserved calls.

  At least one identification reader is provided in the vicinity of the elevator of the at least one elevator group of the elevator system so that the destination control system can confirm the use of the advance reservation call by the correct user. The identification reader may be installed, for example, in the elevator lobby, in front of each elevator, or inside the elevator. Preferably, an identification reader associated with an access gate (eg, a rotating access hub) for a reserved elevator may be provided when a particular elevator is used for pre-reserved calls. This allows only people who make advance reservation calls within a certain period of time, for example within the next 5 minutes, to enter a specific reserved elevator or into a predetermined area reserved within the elevator. It will be.

  Providing an identification reader also has the advantage that a pre-reserved call can be verified when used by a legitimate user, i.e. the user who originated the call. This can be important in connection with the reward system of the destination call control system according to the invention, particularly when the reward system described later is made for individual users.

  If the priorities are user specific, further optional distinction of priorities is possible. In this case, users who have not made pre-reserved calls, users who are not reliable (that is, users who do not use pre-reserved calls at times), and users who use certain pre-reserved calls. You may make a distinction between These group boundaries may be fluid. Therefore, the priority order is determined according to the number of advance reservation calls confirmed in the past or the number of advance reservation calls that have not been used in the past. Each user's priority may be individually adjusted to the user's call history described above.

  In this case, the destination control system has a storage unit for each user's movement history / reservation history so that the user's behavior in relation to the elevator system can be evaluated. This makes it possible to partition the priorities of the destination call controller by means of a relative grouping of users or even assign individual priorities for each user. The travel history may include only the number of times of boarding the elevator system based on a pre-reserved call in a single embodiment. However, the travel history includes additional data such as total boarding times in the elevator system, the relationship of pre-reserved calls to unreserved calls in boarding times, the number of pre-reserved calls that have been confirmed and not used Or it may include the proportion, boarding time of the reserved call, and the like. In this case, the priority of assignment of pre-reserved destination calls may be determined based on the number of pre-reserved calls made by individual users that have been confirmed and / or not used. The individual priority may be, for example, admission permission for a specific reserved elevator (here, it may be several reserved elevators that can be provided with different priorities). Alternatively, it may be the assignment of individual weighting factors to the cost function parameters used in the call assignment algorithm. By using individual weighting factors, shorter waiting times, boarding times and / or total travel times may be assigned to individual users. The priority may be increased by checking each destination call reserved in advance by the user, while decreasing the priority by checking each time the call reserved in advance is not used. May be. Therefore, it is possible to monitor the assignment process of individuals using the elevator group and reward a higher priority in call assignment for re-booking of pre-booked destination calls.

  By the above-mentioned means, the user of the elevator system obtains an immediate reaction from the elevator system regarding the quality of service with respect to the action reserved in advance. This is particularly important for high-rise elevators with a large number of arrival floors, for example 50 floors or more, and may be able to reach destinations in various areas. Such building elevator systems often have several elevator groups serving different areas within the building. Of course, when an elevator group change is required for a call that is pre-reserved for travel within the elevator system, elevators in other elevator groups are also reserved for the pre-reserved call. Thereby, the allotted time will take into account the traveling of the preceding elevator towards the transitional floor of the elevator system being processed by two adjacent elevator groups. Therefore, the elevator group control device may have a multi-group control device that adjusts traveling through several elevator groups. The configuration of the control device for the elevator system, for example, one elevator group control device in the multi-group control device that performs the adjustment and / or division of the elevator group control device that is integrated or separated into several, is predetermined by those skilled in the art. In the process of technology.

  Preferably, an individual priority order may be assigned to each user of the elevator system, and the destination call input device includes a display unit indicating the assigned elevator and the priority order assigned to the user. You may go out. In that case, the user immediately gets information about the status of their priorities in the elevator system.

  The assignment of a given priority to the user not only affects the individual weighting factors for the cost function parameters or the booking of the entire elevator, but also the booking of a given elevator space in at least one elevator in the elevator system. It also has an effect on it. As a result, a sufficient area in the elevator is always reserved for users who have made advance reservations.

  The present invention is advantageous in modern elevators where the number of pre-reserved calls preferably increases with building dimensions and number of arrival floors. As the advance reservation window becomes longer, it becomes increasingly important to use the advanced allocation system of the present invention.

  Pre-booked calls may be categorized and incorporated into a schedule, for example, in light of several other factors for safety or energy saving purposes. The advance reservation system of the present invention can manage people's access rights in a desired way. This ensures that, for example, advance reservation calls made by people with access rights that oppose each other will not be scheduled or assigned to the same elevator.

  The invention also makes it possible to greatly consider the optimization of energy in pre-ordered or pre-reserved calls that are allocated in such a way that the overall energy consumption of the elevator system is minimized. .

  Priorities may be handled by assigning calls that were initially pre-booked. This is because the known energy window in the most energy efficient manner and the immediate calls received thereafter (ie calls that are not pre-booked) are allocated separately to the most suitable available free time left from the pre-bookings. It is. In addition, priorities may be processed by allocating regions in the elevator to the call users initially pre-reserved, and only the remaining regions are allocated for the remaining immediate calls. This ensures that calls that are pre-reserved with a higher priority than calls that are not pre-reserved can be processed.

  Preferably, destination call assignment is performed under the use of a cost function. In the cost function, various allocation parameters comprise various weighting factors that should be considered in the allocation decision. This increases the passenger waiting time and / or boarding time weighting factor of the pre-reserved call relative to the corresponding pre-reserved destination call weighting factor. Through this means, the overall allocation efficiency for pre-reserved calls will be better than for non-pre-reserved calls for passenger waiting and / or boarding. This is a system that can clearly benefit users who reliably use the advance reservation function of the elevator system.

  As has been mentioned above, preferably at least one particular elevator of the elevator group is reserved for pre-reserved calls. And preferably, part of the elevator capacity in the elevator group of the elevator system is reserved for pre-reserved calls. In this case, preferably the number of reserved elevators can be set dynamically according to the variation of the ratio of pre-reserved calls to non-pre-reserved calls.

  Preferably, at least one reserved specific elevator is installed in a restricted access area that is accessible only to users with identifiers associated with pre-reserved destination calls in the near future. The Through this means, unauthorized use of advance reservation calls by unauthorized users can be efficiently prevented, and the advantages of advance reservation calls over immediate calls can be improved. The identification reader is in this case preferably arranged in connection with the access control device, i.e. in connection with a fence or hub in the access control area.

  A destination call input device has a portable device, such as a smartphone, a terminal or a computer, used individually by a user of an elevator system or by a destination input panel arranged in connection with an elevator group. May be. As long as the destination call input device is personal, the destination call input device may be configured to automatically transmit an identifier associated with the pre-reserved call to the destination control system. For example, as long as the destination call input device is publicly available as a destination input panel, the identifier needs to be entered with the pre-reserved call origination. Whatever the scheme, the destination control system has wired or wireless input nodes for various destination call input devices. With such a configuration, reliable and safe input is guaranteed not only for calls not reserved in advance in the destination control system but also for calls reserved in advance.

  The destination control system is usually implemented as a microprocessor system algorithm.

  A destination control system is usually an elevator group control device or a multi-level system that controls several elevator groups in a high-rise building with at least one elevator group or different elevator groups in different areas of the building, for example. Part of the group control device.

  Preferably, the destination control system has an optional part that cancels the pre-reserved call until a preset period before the pre-reserved call activation time. Through this means, the elevator user can cancel the pre-reserved call without reducing the user's priority in the pre-reserved call system. With revocation, pre-reserved calls are removed from the call assignment system before the call operates in the assignment system. Therefore, the default period before the operating time of the pre-reserved call is at least the waiting time of the pre-reserved call or the pre-reserved call before the operating time indicated in the allocation (the desired allocation time). This is the time zone of the assignment algorithm that is input to the assignment system.

  The invention further relates to a method for assigning an elevator call to an elevator of an elevator system having at least one elevator group with several elevators. In this method, a destination call is input to a destination control system via at least one destination call input device and assigned to at least one elevator in the elevator group to process the destination call. In the method according to the invention, the desired working time of a so-called pre-reserved destination call, the destination call data issues the departure floor, the destination floor, the correlated working time for the pre-reserved destination call and the pre-reserved destination call. You may produce | generate so that a user's correlation identifier may be included. According to the present invention, a pre-reserved destination call is assigned a higher priority than a destination call without a pre-reservation and is assigned to an elevator in the elevator group. Then, by processing the pre-reserved destination call, the identifier of the elevator user who issued the pre-reserved destination call is prompted to confirm the legitimate use of the pre-reserved destination call.

  The method provides the same advantages as already mentioned in the destination control system according to the invention. That is, the service provision with higher priority is guaranteed for the destination call that has been reserved in advance compared to the destination call without immediate reservation (immediate call). In the method according to the invention, the use of a pre-reserved call is confirmed by reading the elevator user identifier. Through this means it can be ensured that the pre-reserved call is indeed used by a legitimate person. Furthermore, it can be ensured that the use of pre-reserved calls provides better service in the elevator system compared to immediate destination calls.

  In particular, actively pre-reserving in connection with a specific elevator reserved for pre-reserved calls or a predetermined area within at least one specific elevator reserved for pre-reserved calls Access control may be performed that allows only the calling user to enter the reserved elevator or area. Through this method, it is possible to efficiently eliminate the abuse of advance reservation calls by unauthorized persons.

  Preferably, each user is assigned an individual priority in the use of the elevator system. Thereby, the priority is determined by the number of confirmed pre-reserved calls stored in the storage unit relating to the user service history for the elevator system. This system increases the efficiency of the elevator system for individual persons and provides an efficient use of the advance reservation function. For example, individual priorities may directly affect individual weighting factors of parameters in the cost function of the assignment algorithm, such as passenger waiting time and / or passenger boarding time. Thereby, for users with high priority, the assignment function will give better results for the parameters.

  According to a preferred embodiment of the present invention, the destination control system sends a confirmation message to each destination call input device upon registration of the pre-reserved call granted by the individual destination call input device. This allows the user to see their calls generated by individual destination call input devices such as portable devices, mobile phones, tablets or computers. For this reason, the user of each destination call input device can use the system more comfortably.

  Further in accordance with a further preferred embodiment of the present invention, the destination control system issues a message to the individual destination call input device including the assigned elevator after assigning the pre-reserved call. This means can also improve the service quality of the elevator system for passengers who use individual destination call input devices. Of course, this message may advantageously be issued just before the service time reserved in advance.

  The invention will now be described by way of example in connection with the accompanying drawings.

1 is a schematic diagram of an elevator system having an elevator group, where one elevator is reserved for a pre-reserved call. FIG. 10 is a flow diagram for assignment of destination calls that are pre-reserved and destination calls that are not pre-reserved.

  FIG. 1 shows an elevator system 10 having a first elevator group 12 consisting of four elevators 14, 16, 18, 20. The four elevators are connected to an elevator group control device 22 having a destination control system 24. The further elevator group 26 may also be connected to the elevator group control device 22, and the other elevator group 26 may be arranged in another area of the building. The connection of the further elevator group 26 with the elevator group control device is optional. The elevator group controller 22 has an input node 28, and a destination input panel 30 and individual computers or terminals 32 in each elevator lobby are connected to the input node 28 via a bus or LAN. Further, a wireless access point 34 capable of communicating via an individual portable device 36, for example, a smartphone, is connected to the input node 28.

  The fourth elevator 20 in the first elevator group 12 is a specific elevator reserved for a call reserved in advance. The secured specific elevator 20 is installed in an access restriction area partitioned by the fence structure 38. As a result, an access hub for the fence structure is provided in the vicinity of the identification reader 40 and permits access to the specific elevator 20 reserved only for the user who made the advance reservation call. An ongoing advance reservation call is an advance reservation call to be processed within a predetermined time frame, eg, 5 minutes.

  The elevator system of FIG. 1 operates as follows.

  A destination call is input to the destination control system 24 of the elevator group controller 22 via a destination call input device, that is, a terminal or computer 32, a destination input panel 30, or a portable device 36. In the case of the computer or terminal 32 and the portable device 36, the identifier of the elevator system user may be automatically generated along with the generation of the destination call. The computer or terminal 32 and the portable device 36 also allow the user to enter a desired time for the destination call, which is the time that the destination call is actually active in the assignment system. For example, an elevator system user can make a pre-reservation call from the 85th floor to the first floor at 12:30 at 12:00. This is an advance reservation call that includes the departure floor, arrival floor and even the time at which the allocation should take place. In the case of the terminal 32 or the portable device 36, the identifier can be automatically given. In the case of a general destination input panel 30 including a display unit and a numeric keypad, it is necessary to manually input an identifier. In this case, the destination control system 24 of the elevator group control device 22 reserves the boarding of the specific elevator 20 secured from the departure floor to the arrival floor of the call reserved in advance at 16:30. A user can access a partitioned access area of a particular elevator 20 through a rotating hub that is released after presenting his identification tag to an identification reader 40 provided near the rotating hub. it can. Access to the access area is only possible within a predetermined time frame before the pre-booked call activation time, ie the earliest at 16:20 or 16:25. The destination control system 24 recognizes the departure and destination floors of pre-reserved calls for quite some time. As a result, the allocation of specific elevators 20 that saves energy can be arranged, and the most economical approach will deal with advance reservation calls in time.

  FIG. 2 shows a selectable flow chart for pre-reserved and non-pre-reserved calls. Box 50 is for pre-reserved calls where the elevator system, ie the elevator group controller 22 of the elevator system, obtains the departure floor, destination floor, call assignment operating time and the identifier of the user who made the pre-reserved call. This is the start box. Box 52 is the starting box for calls without prior reservation, i.e., immediate destination calls that include only the departure floor, destination floor and optionally user identification data. In the decision field 54, a decision is made as to whether or not the pre-reserved destination call has been canceled during that time. If canceled, the procedure ends with an end indicator 56. If the pre-reserved call has not been cancelled, the flowchart proceeds to a decision field 58 where the pre-reserved call activation time is compared to the actual time to determine whether the pre-reserved call should be assigned. To do. If it is determined that it should not be assigned, the process returns to field 54. If it is determined that it should be assigned, the flowchart proceeds to decision field 60. Calls that are not pre-reserved go directly from box 52 to decision field 60. In the decision field 60, a decision is made as to whether or not the ongoing call is a pre-reserved call. If it is a pre-reserved call, the flowchart proceeds to a decision field 62 that checks whether the reserved specific elevator 20 has sufficient space to handle the call. If there is enough space, the allocation procedure for this reserved specific elevator 20 is performed in field 64. If there is no space available in a particular elevator 20, the flowchart reads the elevator user identifier from the decision field 62 and obtains the corresponding individual user priority to determine the destination call priority. Proceed to read operation field 66. Each priority assigned to a destination call in the active field 66 is accompanied by a series of individual weighting factors in the active field 68 that better perform the call assignment for each user's pre-reserved destination call. This leads to call assignments for all other elevators except for the specific elevator 20.

  Returning to the third decision field 60 which prompts to determine if the current destination call is a pre-reserved call, and if a negative result is obtained, the cost function corresponding to the low priority of the immediate destination call With normal weighting factors for the parameters, proceed to the operational field 70 where normal call assignment is performed within the range of all elevators in the elevator system except for the specific elevator 20.

  The operation fields 70 and 68 are connected in front of the operation field 72 for displaying the assigned elevator on the display unit of the destination input panel 30 or the display unit of the portable device 36. In the decision field 74, it is instructed again whether or not the pending destination call is a call reserved in advance. If it is not a pre-reserved call, the assignment ends at end field 76. If it is a pre-reserved call, the allocation procedure proceeds to a decision field 78 that directs the determination of whether the pre-reserved call has been confirmed. If the call is confirmed, the priority of each user is increased in the operation field 80. If it is not a confirmed call, the priority of each user is lowered in the operation field 82. Thereafter, the assignment procedure ends at end field 76.

  On the one hand, the above-mentioned allocation method ensures that a user who has reserved in advance obtains a reserved area in the specific elevator 20 if possible. However, if there is no space available, the allocation procedure also gives a better weighting factor to parameters that the passenger can perceive in the cost function of the allocation algorithm, such as passenger waiting time and passenger ride time. Proceed to individual assignments. This provides a better service than an immediate destination call.

  If there is no advance reservation call reservation for a specific elevator 20, the determination field 62 and the operation field 64 can be omitted.

The invention is not limited to the embodiments described above, but can be varied within the scope of the appended claims.
